Alright, my CSI pump is installed and working fine using a relay system. My question is this: I don't want to connect it to the IGM fuse or INJECTOR fuse cause I only want the CSI running if the motor is running. I listen to the radio a lot while waiting with the car off, but I do NOT want the CSI running like that.

 

I can't think of any way to power it only when the engine is actually running. Think about it, key is On all systems must be powered. You stall the car and all systems keep recieving power which is just like turning it to On without hitting the starter, I don't think it would be wise or simple and easy to wire to only run when the engine is running.

I think you should wire it to something switched with the ignition, and use the Accessory key position (key back opposite of On) for what it was designed to do, power only your radio

Another benefit of having it wired to "On" is that you can just turn the key to On to circulate coolant at the track without running the car creating more heat. Some people wire a dedicated hotwire switch for this, but your radio and fuel pump don't drain the battery that fast for occasional track cooling in the On position.
